Who is a good candidate for ultra high profile??
These implants are rarely needed except for reconstruction. Your surgeon no doubt felt they would not achieve your goals and so did not wish to cloud the consent process with irrelevant information. In general the result is equal to what breast tissue you have plus the implant. If you have reasonable breast projection then an ultra high implant may look fake or result in excess pressure on your breast tissue when can lead to thinning out of the breast and subsequent problems in revisional surgery in the future.

Typically, a surgeon will choose whatever implant is the proper dimensions to achieve the end result that patient desires. There is nothing good or bad about one profile versus another, it is just which implant will best meet the goals in that individual patient. Probably, your surgeon did not feel ultra-high was the best choice to give you the end result look you desired.
